Just as it says really ... 
  quiet night in?
 round friends for dinner?
 getting absolutely smashed at your local?
 big night out on the tiles/going clubbing?
 something else? 
 Me, I've got tickets to Ministry of Sound in London to go and watch a number of DJ's - it's gonna be heeuuuuuuuuuuuuuuuugggeeeee! I envisage crawling into bed somewhere around 8am-10am on the 1st 
 
  Please don't try and ring me or speak to me until the 2nd. Thanks.
